Serial No. 772,858.

To all Z whom it may concern Be it known that I, EDMUND B. CULvnn,

a citizen of the United States of America residing at Great Barrington,in the county of Berkshire and State of Massachusetts, have inventedcertain new and useful Improvements in Sewer-Cleaning Devices, of whichthe following is a specification.

My invention relates to that class of pipe and sewer-cleaning hoes inwhich a handle of coupled sections is used with a hoe of hingedsections, inserted into the pipe or sewer to draw the accumulation offoreign matter therein to the man hole, or opening, for removal.

The objects of my invention are, to provide a hoe with a sectional and,where necessary, flexible handle; to provide a hoe which will cut itsway through the accumulated matter when entering the pipe and willinterpose a surface to withdraw said matter when the implement iswithdrawn; to provide a hoe in which the hinged or hoe member may be setat any desired angle when entering the pipe, and to provide a hoe inwhich the hinged or hoe member may be speedily removed to allow a rakeor hook to be brought into play for the removal of rags or the like,which may be pushed ahead of the hoe when entering the pipe andconsequently not caught by the same when being withdrawn.

lVith these and such other objects in view as may hereinafter more fullyappear, the invention consists in the novel construction and arrangementof parts set forth in the specification and claimed in the claims, andwhich are shown in the accompanying drawings, wherein Figure 1 is a planview of the device, the hinged or hoe portion being shown in theposition it assumes when being thrust into a pipe. Fig. 2 is a sideelevation of the hoe section, the hoe and triangular cutting mem berbeing shown in section and the hoe being shown in operative position.Fig. 3 is an end el vation, the hoe being shown in operative position.

Referring to said drawings by numerals, a handle section 1 terminatingin a point 2, has mounted thereon, in any suitable manner, either bycasting therewith or welding or otherwise fastening thereto, thetriangular cutting member or blade 3, provided with a slot or opening 4through which passes the rake or prong 5, carried by the handle 1 andpreferably integral therewith. Said rake or prong 5 acts as a stop orbum-per for the hoe member and also serves to catch rags or the like anddraw them from the pipe or sewer.

Hinged to the triangular portion 3, at the side thereof which lies uponthe handle 1, is the hoe member 6. The hinge pin 7 which connects saidhoe member to said triangular portion being, by preference, a loose pinto permit the hoe member to be easily and rapidly removed when desired.Handle 1 is provided with a threaded recess forthe reception of screw 8,by means of which the angle or position of said hoe member 6 may bevaried as desired. The handle for said implement is sectional, thesections being joined together in any suitable manner but preferably, ashere shown, by means of the threaded sleeves or collar 9 which engagethe threaded ends of the sections. Said sec tions may be solideas shownat 10 or the handle may consist wholly or in part of flexible sections,such as shown at 11, when the same is rendered desirable by reason ofcurves or bends in the pipe.

The device is operated in the following manner: When a pipe is to becleaned, the implement is inserted therein, point first, sections beingadded to the handle until the desired length is attained. During theinsertion of the implement hoe member 6 will rest upon the screw 8, thepoint 2- and edges of members 3 and 6 serving to cut a way through theaccumulated foreign matter which it is desired to remove. Upon startingto withdraw the implement, member 6 will be thrown up against rake orprong 5 and will carry with it the aforesaid foreign matter. Rake orprong 5 serves to catch rags and the like for the purpose of withdrawingthe same from the pipe. In order to facilitate the operation of saidrake or prong, loose pin 7 may be easily removed thus releasing hoesection 6.

Having described my invention, what I claim as new and desire to secureby Letters Patent, is

1. A sewer-cleaning implement consisting of a handle section, atriangular cutting member mounted thereon, a prong mounted on saidhandle member and passing through a suitable opening in said cuttingmember, and a hoe member detachably hinged to said cutting member andadapted to rest against said prong when in operative position.

2. A sewer-cleaning hoe comprising a justably limiting the movement ofsaid hoe 10 handle sect1on, a cutting member mounted member between saidprong point and said thereon said cutting member belng prohandlesectlon.

vided with a recess, a prong carried by said In testimony whereof Ihereunto afiix my handle section and passing through said resignature inpresence of two witnesses.
